A study that was released on Monday claims that signs of ageing appear in your early 20s.
Researchers have determined a person’s “biological age” by using 18 measurements for each of the participants in the study at the age of 38. Some of the people in the study registered as being 30 years of age while others appeared to be as old as 60.
When the researchers analyzed in depth the people who had aged a lot quicker, they discovered that signs of aging were visible even at the age of 26. This is the age when they first began to take biological measurements on people.
These findings are based on the analysis of 954 people who were born in New Zealand in the years 1972 and 1973. The scientists collected information from the metabolism, immune system, dental health, lung, kidney and liver function and blood vessels from the people’s eyes at the ages of 38, 32 and 26. The teams of scientists also analyzed the fitness levels, cholesterol and telomeres length. Telomeres are the caps located at the end of the chromosomes, which serve as protective shells and have been seen to shorten with the time.
Most people in the group were growing old at the normal rate of a biological year for every chronological one, and even less than that. However, there were others that were ageing as quickly as three biological ones for every chronological year. The people who were growing old quicker also had bad results on tests that were typically conducted on individuals over 60 years of age, like solving problems unfamiliar to them, coordination and balance.
A group of students from the Duke University were asked to take a look at photos of the individuals in the study and they pinpointed the people whose bodies were growing old a lot faster than the others as the older individuals of the group.
The authors of the study said that these discoveries will open doors for tests in the future that may become a lot cheaper and easier to apply, in order for individuals to learn exactly how fast they are growing old in their 20s. This is the time when those people may be able to prevent and do something about diseases related to age. Some previous studies revealed that genes are responsible for just around 20 percent of ageing, which means that the rest is up to the environment and people’s behaviors regarding their health.
The study was published on the 6th of July in the Proceedings of the National Academy of Sciences.
